SPECIFICATION forming part of Letters Patent No. 398,159, dated February19, 10889. Application filed May 12,1888. Serial No. 273,652. (Nomodel.)

To all who/1t it 'ntf/7j cm2/cern.-

Be it known that l, THoMAs B. JEEEERY, a citizen of the United States,residing at Ravenswood, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Velocipedes, whichare fully set forth in the following specification, reference being hadto the accompanying drawings, forming a part thereof.

In the drawings, Figure l is a plan of a portion of the principal partsof the frame-work of my improved velocipede, the reach to the forwardsteering-head and the seat-supports being broken off, as well as themain axle outside bearings, so that neither the forward wheel nor theseat nor the drive-wheel is shown. Fig. 2 is a section through the line.r on Fig. l. Fig. 3 is a detail section through the line a," a" on Fig.l. Fig. 4 is a'detail sectional elevation of the clip which holds theseat-support and forms one pvot-bearing for the forward fra-me, thesection being made at y y on Fig. l. Fig. 5 is a detail side elevationof the brake and its operating mechanism. Fig. 6 is a detail elevationof the trailing wheel. 7 is a side elevation of the whole machine.

The rear or principal frame comprises the side bars, A A0, which areconnected in the vicinity of the main axle by the cross-barAS. From thesaid cross-bar are extended the lugs A4 A4, in proximity, respectively,to the side bars, A and A2, but projecting from the crossbar lower downthan said side bars. 'Io the cross-bar A3, about the middle of itslength, I secure a clip, A5, which has the lugA-l projecting forward andslightly upward, so that it affords a bearing in line with the bearingA10 on the side bar A', and in these two bear ings I pivot the reach B,said reach having its length extending forward and being bent slightlyto the right outward, so that it carries the steering-head at theforward end in line with the right-hand drive-wheel. At its rear end isformed a horizontal bracket, B', whose arm B10, extending transversely,constitutes the pivot of said reach, which is journaled in the bearingsA10 A50. The side bar A has the extension A, terminating in thedownwardly-open socket or pocket all, which overhangs the reach B ashort distance forward from its pivot. A coiled spring, C, in-

serted in the socket a and thereby retained in place, rests at its lowerend upon the upper surface of the reach B and tends to force the reachdownward with respect to the side bar A. A link or bolt, c, placedwithin said spring, being connected at the lower end to the reach andpassing through the top of the socket A, is provided with a stop-nut,c', outside of said socket, whereby said link checks the action of thespring and prevents the reach being forced away from the side bar beyonda certain definite distance, determined by theposition of the stop-nut.on the link c.

To the lugs A1A4 are pivoted, respectively, the bars D'D, whichconstitute the pedalcrank-shaft frame, said bars extending downwardlyand forwardly from their said connection to the lugs A4, and having .attheir forward ends the bearings for the pedal-crank shaft D. Thesebearings are held in fixed relation to the side bars, A and A0, by thevertical braces D2 D2, which are secured at one end to the said bars Band at the other end to the side bars, A and A2, respectively. Thecross-bar A3 has another lug, A, which, as illustrated, is located nearthe righthand end of the cross-bar. `It extends downward and rearwardfrom the cross-bar, and to it I pivot a trailing-wheel arm, comprisingthe parts E and E3. Upon the arm E there is clamped the clip E', towhich there is bolted the link E2, the other end of which is bolted to alug, d20, formed on the clip d2, which affords a means of fastening oneof the braces D2. The arm E is preferably made tubular, the lower endbeing split and furnished with lugs c, through which a screw or bolt,e', passes to clamp them together, and into the lower end of thistubular arm there is inserted the spindle E3, which at its lower end hasthe bearings for the trailing wheel E4. The arm E3 is held firmly in thearni E by tightening the clampscrew c, which thus draws together thelugs e and contracts the opening in the tubular arm E, and the positionof the trailing wheel E4 maybe adjusted by telescoping the two parts Eand E3 together and clamping t-he split end of the outer one, E, uponthe inner one, E3, thus making the entire trailing-wheel arm, whichcomprises both'parts E and E3, an extensible arm. The clip E isadjustable to any desired posi- IOO tion on the trailing-wheel arm E,and may be secured at any position by the clamp-screw ew. By sliding theclip up toward the cross` bar A3 the trailing-wheel. arm is caused toextend farther toward the rear as it is thus made to approach thehorizontal position, and by sliding said clip down toward the trailingwheel the latter is drawn forward as the arm is drawn toward a verticalposition. The purpose of this adjustmcmt is to enable the rider to adaptthe position of the trailing wheel to the character of the grouml beingtraversed, for if a perfectly-level .door or track is being traversedthe trailing wheel maybe set quite close to the track; but if very roughgrouml is being traveled over the trailing wheel should stand, farenough from the ground so that it will not collide with suchobstructions as may exist in the irregularity of the surface. If thewheel were thus elevated, by merely telescoping the arm to shorten itthe wheel might necessarily by this movement alone be lifted so high, inorder to pass obstructions, that in case of a rear tilt, tending tothrow the rider over backward, the trailing-wheel arm would reach nearlythe vertical position before the trailing wheel would strike the groundand arrest the tilting movement, so that the rider would be in danger ofbeing thrown over backward. Therefore, when it is necessary thus toraise the trailing wheel from the ground for the purpose indicated, theclip E will be moved up toward the cross-bar A, so that the trailin g-wheel arm will be thrown upward and rearward toward a horizontal.position, and for greater safety it will be extended also by drawing onthe part E, still, however, keeping the trailing wheel far enough fromthe ground. Thus, instead of a shorter radius being obtained for thetrai'lin wheel when it is raised from the ground on account of theroughness of the surface, a longer radius is obtained, so that, althoughthe wheel may be quite a distance from the surface, a very slight changeof angle or tilt rearward will bring it to the ground and arrest suchbackward tilting.

The seat-su p port l is adjusted vertically in the clip Ai, slidingthrough the sleeve A thereon; and the construction here shown adaptssaid elip A5 to serve both purposes already pointed out-'viz., as apivot-bearin g for the front wheel or reach to the steering-head and asau open socket in which the seat-support is held and adjustedvertically.

The steering-handle rod G has its bearing in the boss g, formed upon theclip G which is secured upon the reach A', and may convenientl y be madethe means, also, of connecting the lower vend of the link c to thereach,

shown in Fig. The sidebar A2 is somewhat longer than the sidebar A',being eX- tended forward far enough so that it has the bearings A20 A2for the brake-handle rod H, which is in line transversely with thesteering-handle rod G. For the purpose of simplifying the connection andfastening of said Inzake-lun)dle rod in its bearings, I secure thecollar l-I to the rod ll between the two bearings AU, making it of Vsuchsize as to (ill the space between them, so that when fastened to the rodl-I, as by the set-screw 7i, it stops the rod from longitudinal movementin both directions and prevents the necessity of any other stop collaror pin. At the same time the rod maybe adjusted in it to bring thehandle to any desired height by merely loosenin g the set-screw II andsliding the rod up or down to the collar ll and tightening the set-screwwhen the handle is in the desired position. The collar II has thecrank-arm H10, to which is connected thc brake-rod H2, which operatesthe brake-lever l-I to tighten or slacken the brake-band lI.

The brake-rod Il2 is connected to the crankarm H10 by the universaljoint shown at H5, which permits the said rod to have both the motionsnecessary on account of its connection-one a slight oscillation in ahorizontal plane as the handle Il is rotated and the crank ll10 iscaused to oseillate in a horizontal plane, and the other an oscillationin a vertical plane, caused by the guidance of its rear end by thebrake-lever IP, oscillating about its pivot on the bar I).
